How and why animals develop as male or female is far more complex than we ever imagined.
According to the United Nations, the world’s population could reach 10 billion by 2050.
The UN's new global population projections include some surprises – in particular, that the global population in 2100 will be 3% less than they projected in 2017.
When it comes to reproduction, couple have more choices than ever before.
A ban on clinical trials involving gene editing rules out the controversial procedure done in China. But it also prevents procedures that could offer couples a chance for healthy children without genetic disorders.

Approximately 25% of women – representing all races and backgrounds – will undergo an abortion before the age of 45.
New research shows dolphins have a large clitoris that is similar to the human organ.
It was not until the late 1990s that the anatomy of the human clitoris was accurately described by Australia’s first female urologist. And now research in animals is starting to catch up.
Welcome to the world, little lizard. A three-toed skink (
Saiphos equalis) hatching from an egg.
The evolution of live birth from egg-laying is no mean feat. Now new research reports on the first known example where both eggs and a live birth come from the same lizard pregnancy.
We’re having less sex than we used to.
Australians report having sex once or twice a week, on average, but there are many variables. And that's assuming people's estimates are accurate.
Birds and mammals use feathers and fur for staying warm and dry – but for other purposes too.
Finding a mate is of course essential to produce the next generation. And feathers and fur play key roles in making sure that happens.

Are pretty blue and gold stripes more important than being a bold little swimmer?
Acupuncture might alleviate stress for women undertaking IVF.
A new study has countered old reports acupuncture can improve your chances of having a baby when going through IVF.
The pain of infertility has not changed, even if modern technologies have.
It's 40 years since the birth of Louise Brown, the world's first test tube baby. But our long read explains how infertility has a much longer history.

About 20,000 Californians were once sterilized under state eugenics laws. New research shows Latinos were disproportionately targeted. Is there any opportunity today to address these wrongs?
One of the last two surviving female northern white rhinos.
The death of the last male northern white rhino in the world raises an interesting question: when does a species pass the point of no return?
The echidna has a four-headed penis.
The competition to father young is often most intense behind the scenes.
Research shows that the Y chromosome may be able to protect itself from extinction in the short term. But what about in a future where we all reproduce artificially?
Men and women rate warmth and trustworthiness as very important in their potential partner.

What movies tell us is important in a parter – a nice smile or money – are exaggerations of fundamental evolutionary needs that actually do matter.
What can mating yeast tell us about new drugs?
By exploiting the way yeast cells mate, researchers have figured out a quicker, easier way to identify on- and off-target drug interactions.

Parents' DNA try to manipulate one another in a bid to shape junior in their mould.
Gene drives aim to deliberately spread bad genes when invasive species such as mice reproduce.

Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.
In an ideal world of gender equality and recognition for women’s work, surrogacy could perhaps be part of a paid, legitimate economy.

As the Canadian Fertility and Andrology Society urges the government to consider "compensation" for surrogacy, we need to talk about the implications of this rhetoric for women.
